PHOTOGRAPHIC APPARATUS.

SPECIFICATION forming part of Letters Patent No. 248,179, dated October11, 1881. Application filed June 21, 1881. (No model.)

To all whom it may concern Be it known that I, DAVID I-I. HoUsToN, ofOambria, in the county of Columbia and State of Wisconsin, have inventeda new and Improved Photographing Apparatus, of which the following is afull, clear, and exact description. I

The object of my invention is to facilitate taking a number ofphotographic "iews sue-- cessively and in a short time.

The invention consists in a camera with a receptacle or box at its innerend containing a roll of sensitized paper or any other suitabletissuesuch as gelatine or any more durable material that may bediscoveredand an empty reel, upon which the sensitized band is wound asrapidly as it has been acted upon by the light.

1n the accompanying drawings, Figure l is alougitudinal sectionalelevation of the camera provided with a box containing rolls ofsensitized paper or other suitable material. Fig. 2 is ahorizontalsectional elevation of the same.

A box, K, containing sensitized flexible bands of any suitable material,may be passed into the receptaclein the rear part ofthe camera. This boxK is provided with two vertical rollers or cylinders, L, provided withratchetwheels L, against which a spring-pawl, L rests, attached to frontwall, M. This frontM of the box is provided at the two ends withvertical slots N, and vertical rollers O, pivoted in the box K, arecontained within these slots. A ribbon or band, P, of sensitizedmaterial passes from one roller L, around the roller 0 at thecorresponding end of the box, and then through the corresponding slot,N, along the.

front of the box, through the opposite slot, N, around the correspondingroller, 0, and to the other cylinder L. Before beginning the operationsall the paper is wound on one spool or cylinder L and the other isempty, and the paper is wound from the full cylinder upon the empty oneby turning the latter as the work proceeds. This cylinder is turned bymeans of a key placed on the squared end of the shaft Q of thiscylinder. The box K is provided with a vertical slide, 1t, for excludingthe light from the paper band P, when desired.

The end pieces, S, of the front end frame, T, of the bellows U of thecamera are provided with segmental recesses, into which the outersegmentally-curved edges ofi. the sliding side pieces, V, of the bellowsbox fit, these side pieces being provided with segmental slots X,parallel with the edge of the side pieces, and through these slotsbinding-screws XV pass into the end pieces, S,.of the front end frame,T, and lock this end frame, T, in any desired position on the sidepieces, V, for this end frame swings or turns on the segmental outeredges of the side pieces.

0n the shaft of the left-hand roller 0 there is a pointer, X, outside ofthe box, to show the revolutions of the roller, and the roller is madeto measure in circumference just half the length of the negative, sothat two revolutions of the roller measure tissue enough for onenegative. The same roller 0 carries a sharp point or stud, Y, near itstop or bottom, which pin perforates the edge of the tissue eachrevolution, and consequently every other perforation marks the spacebetween the negatives. As the impressions taken by light are at thistime not developed, it follows that the perforations are necessary tocut the tissues apart for the development of the several negatives.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In aphotographic-cameraattachment, thecombination, with the roller 0, of the pointer X and pin Y,substantially as herein shown and described.

2. In a photographic camera, the combina tion, with the roller 0, of theperforator or pin Y at the bottom or top of the roller, substantially asherein shown and described, and for \the purpose set forth.

3. The combination, with the box K, provided with the slots N in itsfront M, of the roller 0, the rollers L, and a band, I, of sensitizedflexible material attached to the rollers L, substantiallyas hereinshown and described, and for the purpose set forth.

4-. The combination, with the box K, provided with slots N and its frontM, of the rollers O, the rollers L, the ratchet-wheels L, thespring-pawl L and the band, P, of sensitized shown and described, andfor the purpose set forth.

g side pieces, V, of the bellows-box, of the swinging front end, T,substantially as herein shown and described, and for the purpose setforth.
